Heh, you're right. Let's forget about available and do cpuset.cpus.effective. The primary reason for suggesting that was because of the similarity with cgroup.controllers and cgroup.subtree_control; however, they're that way because subtree_control is delegatable. For a normal resource knob like cpuset.cpus, the knob is owned by the parent and what's interesting to the parent is its effective set that it's distributing from.
Thanks.
